Solitary crystals of metals are delicate and malleable, even though polycrystalline metals are tougher and more powerful and are more useful industrially. Most polycrystalline supplies is often made into huge single crystals right after prolonged warmth treatment. In the past blacksmiths would heat a piece of metallic to make it malleable: heat will make a handful of grains increase substantial by incorporating smaller sized kinds.
